It’s nearly five years since the parent company of British Airways, International Airlines Group, acquired bmi British Midland from Lufthansa.
The bmi name was long disappeared from London Heathrow. Its regional arm bmi regional is still flying having been acquired by independent investors.
However, bmi’s frequent flyer programme Diamond Club has remained in operation.
Whilst it hasn’t been possible earn Diamond Club miles from flights, it was possible to earn miles through Diamond Club credit cards issued by MBNA Ltd until 30 September of this year.
Any remaining miles in all Diamond Club accounts will expire in perpetuity on Wednesday 30 November 2016.
However, it is possible to transfer any remaining miles in your account on a 1:1 basis to Avios in a British Airways Executive Club frequent flyer account. This must be done before 30 November 2016.
In order to do this you will need to be able to access your Diamond Club account online (to retrieve your membership number and miles balance) and have an active British Airways Executive Club account.
BA has a dedicated tool on its website called Combine My Avios. You can use this to transfer however many Diamond Club miles you have to your Executive Club account.
A transfer of miles should only take a few minutes to do and should then appear in your Executive Club account shortly afterwards.
On a related note, here’s our analysis, albeit superseded by recent events, of what happened shortly after the merger of bmi into BA.
The Diamond Club website has now closed and it is no longer possible to access Diamond Club accounts. Any mileage balances that have not been transferred or used are now forfeited.
